Study on energy saving of chilled water storage air-conditioning system based on dynamic load tracking

以中原经济区职业教育培训学校水蓄冷空调系统为研究对象,针对实际工程案例,采用配合蓄冷空调动态负荷的跟踪监测系统,相比传统空调系统日平均节约电费为12 704.60$,可转移非低谷电量41.28%。通过对系统负荷进行动态跟踪监测,分析了空调输出负荷与实际所用负荷匹配技术的相关性,以期合理调控空调区域负荷需求、适时提供制冷量,旨在实现系统节能降耗和减少实际开机容量,为类似空调系统的工程设计、运行及空调动态负荷监测的研究提供参考和借鉴。

A practical engineering case is investigated for a chilled water storage air-conditioning system which adopts track mornitoring system of dynamic load. Compared to traditional air-conditioning systems, the studied system can achieve a daily electricity saving of 12 704.60 Chinese Yuan, and can transfer 41% peak electricity usage. By dynamic tracking and monitoring of the system loads, the correlation of the output load and the actually required load is analyzed in order to reasonably regulate the requirement of regional loads, timely provide refrigerating capacity and achieve the aim of energy saving and reduction of actual operating capacity. The conclusions drawn in this study can provide guidance for engineering design, operating and dynamic load mornitoring of air-conditioning system.
